What does 1 Corinthians 6:14 mean?
Paul is commanding, persuading, and urging the Christians at the church in Corinth not to participate in sexual immorality of any kind. Some apparently believed that it did not matter what a Christian did with his or her body, in a warped approach to the idea of grace. In combatting this, Paul has refuted what appear to be clichés of that culture, such as "all things are lawful for me," and "food is meant for the stomach and the stomach for food" (1 Corinthians 6:12–13).Misuse of grace, as in those examples, is rejected completely. Paul insisted in the previous verse that the body of a believer exists for a high purpose. It is meant for the Lord, and the Lord is meant for our bodies. That's why these bodies are not meant for sexual immorality.
It's true, Paul writes, that these bodies will die on this side of eternity. It's also true, that they will be resurrected, just as Jesus' body was resurrected after He died. In other words, death is not the end of even our physical bodies. They will be raised, as Jesus' body was, transformed into an eternal version of ourselves unburdened by sin and free forever from the threat of decay or death.
Why, Paul will argue, would we ever want to use these bodies for sexual immorality if that is their destiny in Christ?
